Walter Isaacson’s biography of Steve Jobs has become Amazon’s best-selling book of 2011, as predicted, despite being released in late October. Considering that the book was released in the final quarter of the year, this achievement is a testament to how strong and supportive the Apple community truly is.

Over 375,000 copies of the biography were purchased during its debut week, which helped Isaacson achieve best-seller status on Amazon for his—and the only—authorized biography of Steve Jobs. If you haven’t already purchased a copy of the book, or are in need of a gift idea, ‘Steve Jobs’ is available on Amazon in a hardcover copy for under twenty dollars. The biography is also available in a digital format on the iBookstore.
